What this question tests
Cost reduction strategy for a large scale payments business, balancing efficiency against service quality and risk.
How to approach it
- Break down operating costs into major categories: transaction processing infrastructure, customer support, fraud prevention, and compliance.
- Identify the largest cost driver, likely transaction processing and customer support at PayPal's scale, as the primary target.
- Propose automating a significant share of customer support through AI powered self service for common issues like disputes and password resets.
- Propose infrastructure efficiency: consolidating redundant systems from past acquisitions and optimizing cloud compute usage.
- Address the risk: cutting fraud prevention or compliance spend could increase losses that outweigh any savings, so protect that budget.
- Set a phased target, for example 20 percent in year one from support automation and infrastructure consolidation, building toward 50 percent over a longer multi year horizon with more structural changes.
What a strong answer includes
- Breaks costs into named categories rather than proposing a vague across the board cut with no specificity.
- Explicitly protects fraud and compliance spend, recognizing that cutting there could increase losses larger than the savings.
- Gives an illustrative number, e.g. assumes AI self service could resolve 40 percent of support tickets currently requiring a human agent.
- Proposes a realistic phased timeline rather than claiming 50 percent is achievable immediately, showing grounded judgment.
Common mistakes
- Proposing to cut fraud prevention or compliance spend without acknowledging the risk this creates.
- Giving a vague 'cut costs everywhere' answer with no specific cost category targeted.
- Claiming an unrealistic timeline for achieving 50 percent reduction with no phasing.
Likely follow-up questions
- What would you protect from cuts no matter what?
- How would you validate AI self service does not hurt customer trust?
- What is the biggest risk in this cost reduction plan?
